Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0017] Such as Figure 1-Figure 4 As shown, a BMC reflector mould, a positioning bump 4 is added on the slider 1, and the positioning bump 4 protrudes from the contact surface of the slider 1 and the fixed mold insert 2 to the direction of the fixed mold insert 2 , the fixed mold insert 2 is provided with a positioning groove 5 corresponding to the positioning protrusion 4 , and the positioning groove 5 is used to accommodate the positioning protrusion 4 .

[0018] According to requirements, the cross-section of the positioning protrusion 4 can be square, and the four corners of the square are provided with chamfers; the cross-section of the positioning protrusion 4 can also be circular.

[0019] In terms of technology, the positioning protrusion 4 and the slider 1 are preferably integrally formed.

[0020] In the present invention, by adding pos...

Abstract

The invention discloses a BMC (Bulk Molding Compound) reflector mold, and belongs to the field of lamp molds. In the BMC reflector mold, a locating convex block is additionally arranged on a sliding block; the locating convex block convexly extends towards a fixed mold insert from a contact surface of the sliding block and the fixed mold insert; a locating slot corresponding to the locating convexblock is formed in the fixed mold insert; and the locating slot is used for containing the locating convex block. According to the BMC reflector mold disclosed by the invention, by the additional arrangement of the locating convex block on the sliding block, the fixed mold insert is arranged in the locating slot matched with the locating convex block, so that the sliding block and the fixed moldinsert can be prepared for locating to improve the installation precision of a BMC reflector.

Description

technical field [0001] The invention relates to the field of lamp molds, in particular to a BMC reflector mold. Background technique [0002] BMC material is the abbreviation of Bulk molding compounds, that is, bulk molding compound, which is often called unsaturated polyester bulk plastic mold in China, and has good physical properties, electrical properties and mechanical properties. The BMC injection mold is somewhat different from the usual thermoplastic and thermosetting injection molding, mainly because the shrinkage rate of BMC is low, which is only one-third of the dryness. [0003] BMC reflector products generally have poor side mounting structure and unqualified light distribution. The main reasons for the analysis are: the X / Y / Z positioning of the side screw columns requires an error of less than 0.1mm, which cannot be achieved by the actual BMC mold. The reflective surface is on the fixed mold side, and the side screw columns are on the moving mold side. . Co...
